Auto AK-107 is an autoflowering hybrid from 710 Genetics that blends ruderalis with indica and sativa heritage to create a compact, fast-maturing plant with classic AK-family punch. Designed to finish from seed in roughly 70–85 days under an 18–20 hour light schedule, it aims to deliver reliable production without the need to flip to 12/12. Growers often seek Auto AK-107 for its balanced, energetic-yet-composed effects and its resilient growth habits that suit both new and experienced cultivators.
Autoflowering cultivars like Auto AK-107 are valued for their calendar-driven growth and reduced photoperiod management. This allows indoor growers to run perpetual harvests and outdoor growers to stagger plantings across the season. The strain’s heritage—ruderalis/indica/sativa—reflects its stability, broad appeal, and the breeder’s intent to harmonize vigor with nuanced flavor.
Because 710 Genetics cultivars often target consistency across environments, Auto AK-107 tends to demonstrate uniform structure and internode spacing. This helps with canopy control in tight spaces, micro-tents, and stealth grows. In many reports, it finishes medium in height, making it an apt choice for small grow boxes and balcony setups.
Expect a sensory profile that speaks to the AK lineage: peppery spice, herbal wood, and citrus-sweet highlights layered over a resinous backbone. Its terpene composition typically centers on myrcene and caryophyllene, with limonene and terpinolene often present. This combination contributes to an aroma that is at once comforting and invigorating, with a taste that lingers.
For growers who track data, Auto AK-107 slots into the sweet spot of modern autoflowers: 350–500 g/m² indoors in optimized conditions and 40–120 g per plant outdoors, depending on season length and sunlight intensity. THC levels in AK-derived autos commonly range from 15–21% with CBD typically under 1%, placing its potency solidly above average. These numbers vary by phenotype, feeding, and environment, but they provide a realistic baseline for planning and expectations.
Breeder Background and History of Auto AK-107
710 Genetics, a breeder known for compact, flavorful hybrids, developed Auto AK-107 to bring the classic AK experience into a rapid, low-maintenance format. The name signals an AK-family influence while highlighting an updated, carefully selected autoflowering backbone. Their choice to work with ruderalis reflects a broader European trend toward fast finishes in variable climates.
Auto strains surged across Europe in the 2010s, where shorter summers and unpredictable weather pushed breeders to prioritize speed and resilience. 710 Genetics responded by stabilizing autoflowering lines that produced consistent bud quality in 10–12 weeks from seed. Auto AK-107 embodies that push for efficiency, finishing in the same window without sacrificing organoleptic depth.
The strain’s development focused on three goals: reliable auto expression, balanced hybrid effects, and high resin production for modern extraction methods. This trifecta aligned with consumer demand trends showing preference for concentrates and elevated terpene content. Refining the cultivar required multiple generational selections to lock in day-neutral flowering and uniform morphology.
While specific parent cuts aren’t publicly disclosed, the phenotype clearly echoes the AK identity established in the 1990s, updated with autoflower genetics for modern cultivation. As with many house lines, 710 Genetics optimized for compact stature to appeal to micro-growers and indoor hobbyists. The result is a run-ready cultivar that slots smoothly into grow tents and small rooms.
Grower feedback helped iteratively refine the line, especially around early vigor and tolerance for training. Many early autos were sensitive to topping and stress; subsequent selections improved stress tolerance without extending harvest windows. Auto AK-107 reflects those incremental gains in vigor and predictability.
Genetic Lineage and Breeding Rationale
Auto AK-107’s listed heritage—ruderalis/indica/sativa—describes a balanced hybrid anchored by day-neutral flowering from Cannabis ruderalis. The sativa influence typically contributes to a crisp, head-forward uplift, while indica structure provides denser, more manageable colas. Together they stabilize a morphology that is medium height with moderate internode spacing.
Although the breeder has not disclosed the precise parents, AK-line autos are commonly derived from AK-47-type genetics crossed to stabilized ruderalis. The resulting offspring are repeatedly backcrossed and selected to reinforce both the AK flavor/effect signature and consistent autoflowering. That process typically requires multiple filial generations to remove photoperiod sensitivity and to homogenize bud structure.
The rationale for this cross architecture is practical: lock in the AK-family spice-citrus profile and robust hybrid potency while compressing the life cycle. Stable ruderalis expression allows the plant to transition to bloom based on age rather than day length, streamlining cultivation for beginners and advanced growers alike. This also makes outdoor runs in higher latitudes more feasible.
In phenotypic terms, Auto AK-107 tends to express broadleaf-dominant leaves early, transitioning to hybrid leaf shapes as pre-flower sets. This tracks with the indica influence in vegetative vigor and the sativa input in floral elongation. The overall target is a balanced chemotype with a terpene ensemble that remains faithful to AK family traits.
The genetic design anticipates strong apical vigor but tolerates low-stress training to expand lateral sites. Selecting for a naturally even canopy helps reduce the need for aggressive techniques that can stall a fast auto. In practice, successful phenos often show uniform cola size, making trimming and drying more straightforward.
Plant Morphology and Visual Appearance
Auto AK-107 generally reaches 60–100 cm indoors under 18–20 hours of light, with most phenotypes leaning toward the 70–85 cm range. Outdoor heights vary based on season and pot size, often reaching 90–120 cm in warm, long-day environments. Internodes are moderate, supporting a compact but not crowded structure that takes well to leaf tucking.
Leaves begin broad and dark green, with a semi-matte finish indicating good chlorophyll density. As the plant matures, secondary branches develop sufficient strength to hold up elongated colas without heavy staking. In flower, the buds present as medium-dense, conical clusters with a moderate calyx-to-leaf ratio.
Trichome coverage ramps up quickly in mid-flower, producing a frosted look by day 40–50 from seed. Pistils range from cream to ember-orange by late bloom, with 10–30% amber trichomes marking peak ripeness for many growers. The resin lines the sugar leaves, making them suitable for dry sift or ice water extraction.
Color expression can include lime-to-forest green calyxes with occasional anthocyanin blush under cool night temperatures. These cooler hues typically emerge when night temps drop 5–7°C below day temps in late flower. While not guaranteed, the contrast creates a photogenic finish many hobbyists value.
Bud density is heavily influenced by environmental control, particularly VPD and light intensity. Under optimized PPFD (700–900 µmol/m²/s in flower) and adequate nutrition, the buds fill out with a firm, resin-heavy structure. Under low light or deficient feeding, the buds remain looser but maintain their aromatic profile.
Aroma and Flavor Profile
Aromatically, Auto AK-107 evokes spicy pepper, herbal wood, and a zesty citrus top note that lifts the bouquet. Grinding reveals deeper layers of pine, cardamom, and a faint floral sweetness reminiscent of clover honey. The overall effect is clean, bright, and slightly pungent without being overwhelming.
On the palate, the first impression is citrus-peel bitterness balanced by sweet resin and peppercorn. The mid-palate unfolds with cedar, green tea, and a hint of licorice, suggesting caryophyllene and myrcene interplay. The finish is long, with a cooling eucalyptus-like tail that cleanses the palate.
Vaporization at 175–185°C highlights limonene and terpinolene brightness along with gentle floral volatiles. At higher temperatures (195–205°C), the pepper and wood deepen while sweet base notes persist. Combustion amplifies the spice, producing a classic AK-style room note that lingers.
Cure length significantly affects the profile, with 3–4 weeks of slow cure rounding off sharper terpenes and enriching sweetness. Moisture activity around 0.58–0.62 a_w and jar humidity of 58–62% RH tend to preserve top notes well. Over-drying beyond 55% RH mutes citrus elements and accentuates woody bitterness.
Freshly harvested samples can smell greener and more herbaceous due to residual chlorophyll and volatile alcohols. Proper drying at 18–21°C with 50–60% RH for 7–10 days lets the bouquet stabilize. Once cured, the blend of spice, citrus, and resin is both familiar and distinctive within the AK family.
Cannabinoid Composition and Potency
Autoflowering AK-line cultivars frequently test in the 15–21% THC range, with standout phenotypes exceeding 22% under optimal conditions. For Auto AK-107, grower reports and analogous AK-derived autos suggest a typical THC band of 16–20%. CBD usually remains low, commonly between 0.05–0.8%, placing the chemotype firmly in the THC-dominant category.
Minor cannabinoids such as CBG and CBC appear in trace-to-moderate amounts, often 0.2–0.8% for CBG and 0.05–0.3% for CBC. These minor constituents can subtly modulate perceived effects even at low percentages. Total cannabinoids frequently accumulate to 18–23% in optimized runs across autos of similar pedigree.
Potency is influenced by harvest timing; pulling at peak cloudy trichomes with 10–20% amber often yields the brightest headspace. Allowing more amber development can deepen body effects at the cost of some perceived cerebral sharpness. Light intensity, DLI, and nutrient sufficiency have measurable impacts on resin density and cannabinoid content.
From a comparative standpoint, global commercial flower averages often hover near the mid-to-high teens for THC, placing Auto AK-107 near or above typical dispensary stock. Well-run indoor cycles with stabilized environmental control can push potency into the upper band of its range. Outdoor results vary more widely due to UV exposure, temperature swings, and nutrient variability.
For consumers, it is wise to anticipate a strong but manageable potency curve, especially in the first 30–60 minutes post-consumption. Tolerance, set, and setting all shape the experience, but the underlying chemistry points to a versatile daytime-to-evening profile. As always, batch-specific COAs provide the most accurate potency data.
Terpene Profile and Aromatic Chemistry
Auto AK-107’s terpene spectrum typically centers on beta-myrcene and beta-caryophyllene, with contributions from limonene and terpinolene. In AK-derived autos, total terpene content often falls between 1.2–2.5% by weight, depending on cultivation and cure quality. Samples with higher total terpene content tend to present a richer, more layered nose and finish.
Myrcene commonly registers around 0.4–0.8%, imparting earthy-sweet and herbal notes while contributing to the strain’s relaxing undertone. Caryophyllene in the 0.2–0.4% range brings peppery spice and interacts with CB2 receptors, potentially affecting perceived body comfort. Limonene at 0.1–0.3% underpins the citrus accent and may contribute to mood-elevating impressions.
Terpinolene, though variable, supplies piney and slightly floral high tones that brighten the bouquet. When present above 0.1%, it can shift the nose from purely spicy-citrus to more complex, tea-like aromatics. Humulene and ocimene appear intermittently, adding woody dryness or green-fruit freshness.
Environmental control strongly influences terpene retention. Lower drying temperatures (18–21°C) and moderate humidity (50–60% RH) limit volatilization losses that can exceed 30% if dried too hot. Gentle handling, minimal late-flower defoliation, and careful trimming further preserve volatile fractions.
Nutrient management also affects terpene synthesis, with mild phosphorus stress late in bloom sometimes correlated with elevated secondary metabolite expression. However, excessive stress risks yield loss and inconsistent quality. Many growers aim for balanced nutrition and incremental EC reductions near harvest to protect flavor.
Experiential Effects and Use Cases
User experiences with Auto AK-107 often describe an initial uplift and mental clarity within 5–15 minutes of inhalation. The onset is typically accompanied by sensory brightening, mild euphoria, and a noticeable but not overwhelming energy. As the session progresses, a calm body tone settles in without excessive sedation.
Duration commonly spans 2–3 hours for inhaled routes, with a tapering tail that remains functional for tasks. The balanced profile makes it suitable for daytime creative work, social activities, or focused chores, depending on dose. At higher doses, the body effects deepen and couchlock becomes more likely, especially later in the day.
Compared to heavy indica-leaning autos, Auto AK-107 retains more mental agility and sociability. This places it in a versatile category favored for both solo and group settings. Sensitivity to caffeine pairing varies; many users find the combination synergistic, while others may prefer it alone.
New consumers should begin with small inhalations and wait several minutes to assess potency before continuing. Experienced users often report a consistent, repeatable response that makes dosing predictable across sessions. The flavor encourages slow sipping rather than rapid intake, which may help with moderation.
For music, light exercise, cooking, or structured creative tasks, this strain’s focus and mood-lift can be advantageous. As effects wane, the gentle relaxation can transition well into evening routines. Individuals prone to anxiety with high-THC sativas may find Auto AK-107 more forgiving due to its balanced body component.
Potential Medical Applications
While formal clinical data on Auto AK-107 are limited, its chemotype suggests potential for mood support and stress modulation. The combination of THC with limonene and myrcene is often associated with reduced perceived stress and improved relaxation in user reports. Caryophyllene’s CB2 activity may contribute to perceived reduction in bodily discomfort for some patients.
For individuals managing mild to moderate pain or muscle tension, the strain’s middle-of-the-road body effect can offer relief without heavy sedation. This may suit daytime use where functionality is important. Duration of relief for inhaled routes often lasts 2–3 hours, aligning with general THC pharmacokinetics.
Appetite stimulation is common with THC-dominant cultivars, potentially aiding those facing appetite loss. The uplifting headspace may also be useful to those experiencing low motivation. However, individuals with THC sensitivity or predisposition to anxiety should titrate cautiously.
Sleep outcomes vary; some find that a moderate evening dose eases pre-sleep restlessness, while others prefer heavier indica profiles for insomnia. For sleep, extending the cure and harvesting at slightly higher amber trichome ratios can deepen the sedative tail. Vaporization at lower temperatures may reduce raciness for sensitive users.
As with any medical use, consultation with a healthcare professional is recommended, particularly for those on concurrent medications. Batch-specific lab results, especially cannabinoid and terpene data, help patients tailor choices to their needs. Tracking personal responses in a log can refine dosing strategy over time.
Comprehensive Cultivation Guide: Environment and Planning
Auto AK-107 thrives in a controlled environment that maintains 24–26°C daytime temperatures and 20–22°C nights during most of the cycle. Relative humidity targets of 60–70% in early growth, 50–60% in mid-vegetative, and 45–55% in flower help manage VPD. Aim for VPD ranges of 0.8–1.2 kPa in veg and 1.2–1.6 kPa in bloom.
Light schedules for autoflowers are straightforward: 18/6, 20/4, or even 24/0 throughout the life cycle. Many growers settle on 20/4 for a balance of growth and energy efficiency, targeting a DLI of 35–45 mol/m²/day. In practical PPFD terms, this translates to approximately 500–650 µmol/m²/s early and 700–900 µmol/m²/s in late flower under LED.
Soil and soilless media both perform well; buffered coco with perlite (70/30) offers rapid growth and precise feeding. In soil, choose a lightly amended base to avoid early nitrogen excess that can stall autos. Hydroponic systems deliver fast results but require diligent pH and EC control to avoid nutrient swings.
Indoor pot sizes of 11–20 liters (3–5 gallons) are optimal for yield without overextending vegetative time. Outdoor, 20–40 liters provide a good balance of root volume and portability. Fabric pots improve oxygenation and reduce overwatering risk compared to rigid plastic.
Plan airflow with at least one oscillating fan per 1.2 × 1.2 m footprint, creating gentle leaf movement without windburn. Carbon filtration is advised, as AK-derived aromas can be assertive in late flower. For CO2 enrichment, 800–1,000 ppm can enhance growth at higher PPFD, but it is optional and should be paired with strong environmental control.
Cultivation Guide: Germination to Early Vegetative
Germinate seeds using a 24–26°C environment with stable moisture—paper towel, starter plugs, or lightly moistened seedling mix all work well. Most seeds crack within 24–72 hours, with taproot emergence indicating readiness for transplant into final containers. Autoflowers generally prefer being sown directly into the final pot to avoid transplant shock.
During the first 10–14 days, maintain gentle light at 250–350 µmol/m²/s and RH around 65–70%. Overpowering seedlings with high PPFD or low humidity can stunt early growth and shorten the overall plant. Keep media evenly moist, not saturated, and avoid heavy feeding until true leaves expand.
Nutrient strength for seedlings should remain low—around 200–300 ppm (0.4–0.6 EC) with a balanced N-P-K and essential micros. In coco, start calcium-magnesium supplementation at 0.3–0.5 mL/L to prevent early deficiencies under LEDs. Maintain pH at 5.8–6.0 for coco/hydro and 6.3–6.7 for soil.
By days 14–21, plants typically show strong apical growth and begin forming pre-flower. Increase PPFD to 400–500 µmol/m²/s while keeping temps near 24–25°C. Begin gentle low-stress training once the fourth node is established to open the canopy.
Avoid topping unless the cultivar demonstrates exceptional vigor and you have experience timing the cut early (around node 3), as autos can stall. LST and leaf tucking are safer and often achieve comparable colas without growth interruption. The goal is to expose lateral sites without creating high-stress responses.
Cultivation Guide: Training, Nutrition, and Irrigation
Low-stress training from days 18–28 helps shape an even canopy and maximize light distribution. Use soft plant ties to bend the main stem laterally, promoting multiple primary sites. Reposition ties every 2–3 days as new growth emerges to maintain a gentle, progressive shape.
In mid-vegetative growth (days 21–35), ramp nutrients to 500–700 ppm (1.0–1.4 EC) with a nitrogen-forward profile. Keep calcium and magnesium consistent, especially under high-intensity LEDs where demand is elevated. Watch for early signs of deficiency—interveinal chlorosis for magnesium, rust spotting for calcium—and address promptly.
Irrigation strategy depends on medium; in coco, frequent smaller irrigations to 10–20% runoff maintain stable EC and pH. In soil, water to full pot weight and let the container dry to roughly 50–60% of that weight before watering again. Overwatering young autos can compress the root zone and reduce final yield.
As pre-flower sets, transition to a bloom-leaning feed with a balanced N reduction and increases in P, K, and sulfur. Many growers target 700–900 ppm (1.4–1.8 EC) in early bloom, stepping to 900–1,100 ppm (1.8–2.2 EC) in peak flower if the plant tolerates it. Always read leaf tips for burn; slight tip singe is acceptable, but clawing or deep burn indicates excess.
Maintain canopy PPFD around 600–800 µmol/m²/s during the stretch to manage internode length. Keep RH near 55–60% with strong airflow to prevent botrytis in denser phenotypes. Defoliate lightly, removing only leaves that block key sites or restrict airflow; heavy defoliation can stall autos.
Cultivation Guide: Flowering, Ripening, and Harvest
Autoflowering stretch usually occurs between days 25–45 from seed, with height gains of 40–80% depending on phenotype and intensity. Stabilize the canopy and gradually increase PPFD toward 700–900 µmol/m²/s as pistils proliferate. Keep day temps at 24–26°C and night temps at 20–22°C to maintain metabolic pace.
In mid-flower (days 45–60), bud set is obvious and resin begins to pile on. Monitor EC closely; Autos like Auto AK-107 often perform best with steady, moderate feeding rather than aggressive spikes. Maintain pH targets consistently to avoid lockout near peak demand.
Aromas intensify markedly in late flower; ensure carbon filtration is sized correctly for your space. Reduce RH to 45–50% to protect against mold as colas firm up. This is also a good window to introduce gentle support stakes if colas lean.
Ripening typically occurs between days 65–80 from seed, with most phenotypes finishing 70–85 days. Trichome assessment is the primary harvest driver: many growers aim for mostly cloudy with 10–20% amber for balanced effects. For a heavier body emphasis, let amber rise to 20–30% while watching for terpene fade.
Optional pre-harvest flush can be implemented for 5–10 days in soilless setups, using pH-balanced water to draw down residual salts. In living soil, reduce or cease topdressing and water normally to avoid disrupting soil biology. The goal is clean-burning, aromatic flower with minimal harshness.
Post-Harvest Handling, Curing, and Storage
After cutting, remove large fan leaves and hang branches whole for a slower, more even dry. Aim for 18–21°C and 50–60% RH with gentle, indirect airflow for 7–10 days until small stems snap rather than bend. Drying too quickly can reduce terpene content and lead to brittle texture.
Once dried, trim to preference and place flower in airtight jars filled to roughly 70–80% capacity. Burp jars daily for 10–15 minutes during the first week, then every other day for the second week. Target a stable jar RH of 58–62% for optimal cure and smoke quality.
A 3–4 week cure dramatically improves flavor integration and smoothness, with continued gains up to 6–8 weeks for many batches. Avoid opening jars excessively after the initial phase to preserve volatiles. If RH creeps above 65%, leave jars open longer or use desiccant controls.
For long-term storage, keep jars in a dark, cool place at 15–18°C to slow degradation. Properly cured flower can retain most of its aromatic profile for several months when shielded from heat, light, and oxygen. Avoid refrigeration or freezing of jars with loose flower to prevent condensation damage.
If preparing material for extraction, consider a shorter cure window to retain lighter monoterpenes favored in certain concentrates. Alternatively, fresh-frozen material preserves the live profile for ice water hash or hydrocarbon extraction. Match post-harvest handling to your intended end product.
Common Pitfalls, Troubleshooting, and Integrated Pest Management (IPM)
Common pitfalls with Auto AK-107 include overfeeding early, overwatering in large containers, and heavy defoliation that stalls growth. Because autos are time-bound, recovery windows are short, and any stress can reduce final yield. Gentle, consistent care is generally more productive than aggressive interventions.
Nutrient issues to watch include calcium/magnesium deficiencies under LED, which present as rust spotting and interveinal yellowing. A cal-mag supplement at 1–2 mL/L typically prevents these problems, especially in coco. Maintain pH in the proper range to avoid lockout—5.8–6.0 for hydro/coco and 6.3–6.7 for soil.
Pest pressures in indoor grows often center on spider mites, fungus gnats, and thrips. Proactive IPM with sticky traps, weekly visual inspections, and sanitation reduces risk significantly. Biological controls such as Bacillus thuringiensis israelensis for gnats and predatory mites (Neoseiulus californicus, Phytoseiulus persimilis) for spider mites are effective and compatible with bloom.
Environmental imbalances can invite powdery mildew or botrytis; sustain airflow across and above the canopy and avoid RH spikes. Dehumidifiers and variable-speed fans help maintain stable VPD in late flower. Remove heavily infected material promptly and adjust conditions to prevent recurrence.
For troubleshooting yields, check the following: light map for uniform PPFD, pot size relative to plant vigor, EC stability across the week, and canopy density. Adjust training to reduce shading and ensure even bud development. With tuned basics, Auto AK-107 can reliably meet the 350–500 g/m² indoor benchmark under modern LEDs and attentive care.
